'Be it known that I, ELIsHA N. Fate's, a citizen of the United States, residing at Dayton, in the county. of Montgomery'and shown here is disclosed as-dependingmore particularly on theheat from the exhaust gases of an internal combustion engine it will be obvious that I do not limit m invention to'such application as the device is applicable-to any system where the gases which are to be the source. from which heat is to be derived, whether exhaust or other gases, are moving'at an appreciable velocity.

It 'isthe general purpose of my invention to utilize a simple phenomenon of, aerody-- namic forces to provide for the circulation of heating gases through a heater. I

It is the articularpurpose of my invention asdisc osed to utilize this aerodynamic phenomenon to provide for the circulation of the exhaust gases of an internal combustion engine or the like through a heater. This heater may be used to warm an interior compartment of an automobile, aircraft, motor Y vehicle or may be used to warm any part of. the same, as for instance the water of the cooling circulation system or the intake manifold of the engine of such a "vehicle. Other andmore specific objects of my vention will be found in theaccompanying s cification as it progresses and will be disc osed' in the accompanying drawings, in which-' Fig. 1 is a vertical sectional view'throu h the compartment to be heated showing t e v two 'posltions of the heate'rin elevation.

- Figure 2 is an enlarged section through the heater, su ply pipe and the inlet and exhaustpi s owing the heater in position (heat 011?. Figure 3 is a plan view of the device as. shown in Fi 1 showing theheater in inoperative position (heat oif) g Flgure 4 's anothermodification showing be noted that like reference numerals will i inlet and exhaust pipes from heater as distinct-and separate.

be used for like parts in the various modifi- 2 and 3, around or through the exhaust pipe 7 3 there is provided a suitable plug 11 adapted toact as a bearing for the pipe 6. Pipe 6 is rotatably mounted in this bearing and has an arm 6' integral therewith or secured in any approved manner to the bearing portion of pipe 6 and extending at right an lesthereto. I

he arm. 6 is rigidly securedinan approved manner to a-heater 2 forwhich it acts as a support. This arm 6 is provided the opposite and opens intothe heater through exhaust port 7. The heater is adapted, when out of action to rest within a recess 8 of wall l and is separated therefrom by fireproofing material 9. When it is de sired to move the heater into operatin 'position the handle 10 is grasped an the heater moved out of the recess, the heater rotating on arm 6 around the center of the bearing ortion of pipe 6.

Centra ly mounted within pipe 6, is a second and smaller pipe 4 which extends substantially the length of said pipe 6 reaching to a point 4 well within the interior of the heater and has at its other end an elbow opening into pipe 3 in a direction diametrically opposite port 7. Pipe 43 will hereinafter be referred to as the inlet pipe and pipe 6 as the outlet pi e.

Reference toigure 3 will disclose the fact that. when the heater isolit of operative position the inlet pi e faces at right angles to the flow of gas t rough the pipe 3 with the result that there is no flow of gas through pipe vWith a port7, which opens into pipe 3, while" 4. The rush of gases past the port 5 of pipe 4 would in fact create a slight suction therein rather than causing a flow .of gases into said pipe. The outlet pipe 6 exhaust pipe conducting position however it will be noted that the inlet port 5 faces upstream of the flow of the gases in the supply'pipe 3 causing a rush of gases through pipe 4 to the heater with the desired results. The port 7 of the outlet pipe 6 will at the same time be swung into a osition facing down stream of the exhaust with the result that the rush of gases in the supply pipe past said port will create a low pressure area in the pipe with the result that the circulation of the gases through the heater will be further insured.

In the modification shown in Fig. 4 the heater is'stationary and the inlet pipe 4 rotatably bearsin a bearing plug 11 in the 3 and a'bearing 12 in the heater. It is provided with a handle 10 to provide for its rotation when desired to throw the heater into or out of action. The outlet pipe 6- is fixedly mounted and extends rearwardly with its outlet always facing down stream of the air flow past the moving vehicle having no contact with pipe 3.

I claim 1. In combination with a supply pipe for hot gases in motion, a heater, and means for thegases back and forth between said supp y pipe and heater embodying inlet and outlet pipes having ports in constant communication with said supply pipe and adapted to be turned into and out of line with the flow of gases through said supply pipe.

2. In combination with a supply pipe for hot ases in motion, a heater, and means for con noting the gases back and forth between said supply pipe and heater embodying inports let and outlet pipes arranged one within the other having ports in constant communication with said supply pipe and adapted to be turned into and out of line with the flow of gases through said supply pipe.

.3. In combination with a supply pipe for hot gases in motion, a heater, and means for conducting the gases back and forth between said supply pipe and heater embodying inlet and outlet pipes having ports in constant communication with said supply pipe and adapted to be turned into and out of line with the flow of gases through said supply pipe and means for turning said inlet and outlet pipes.

4:. In combination with a supply pipe for hot gases in motion, a heater, and means for conducting the gases back and forth between said supply pipe and heater embodying inlet and outlet pipes having ports in constant communication with said supply pipe, said facing in diametrically op osite directions, and adapted to be turned into and out of line with the flow of gases through said suppl pipe.

5. n combination with a supply pipe for hot gases in motion, a heater, and means for conductin the gases back and forth between said supp y pipe and heater embodying insignature. I
